Ozone depletion in the stratosphere is classified as what type of problem?

Ozone depletion in the stratosphere is classified as a global problem due to its widespread implications for the Earth's environment and human health. The depletion of the ozone layer affects the entire planet, as it leads to increased levels of ultraviolet (UV) radiation reaching the Earth's surface. This can result in higher incidences of skin cancer, cataracts, and harm to various ecosystems, including marine life and terrestrial plants.

The nature of the ozone layer's depletion is not confined to a specific locale or region; it occurs at a high altitude and affects the atmosphere in a way that transcends national boundaries. The actions taken in one country can influence ozone levels globally, highlighting the interconnectedness of environmental issues. Since the consequences of ozone depletion are felt worldwide, addressing it requires international cooperation and adherence to agreements like the Montreal Protocol, which aims to phase out substances that deplete the ozone layer. This underscores the classification of ozone depletion as a global problem, affecting all nations and requiring a concerted global response to mitigate its effects.
